https://api.x402lint.dev/v1/scan

answers 402

Paid ($0.05). ALWAYS runs a fresh 25-check scan of the origin (non-settling GET/HEAD + benign empty-POST probes), bypassing the 24h cache — use free GET /v1/report to read the cached result. Concurrent requests for the same origin join the in-flight scan rather than double-scanning. Returns grade, score, per-check status + evidence + fix instructions, and a shareable report URL. Unreachable/broken

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
